Abstract :
This study proposed new estimators to estimate the noise level and TEOAE/noise, which are important indicators of the reliability of the recorded TEOAEs. Fifteen normal ears were tested to evaluate the performance. Results showed that the standard deviations of the proposed estimators were smaller than those of typical estimators.
